4-(1,3-Benzothiazol-2-yl)thiophene-2-sulfonamide (4a) was found to be a moderately potent inhibitor of cyclin-dependent kinase 5 (cdk5) from a HTS screen. The synthesis and SAR around this hit is described. The X-ray coordinates of ligand 4a with cdk5 are also reported, showing an unusual binding mode to the hinge region via a water molecule.
4-(1,3-苯并噻唑-2-基)噻吩-2-磺酰胺(4a)在高通量筛选中被发现是一种中等强度的细胞周期蛋白依赖性激酶 5(cdk5)抑制剂。本文描述了该苗头化合物的合成和 SAR 研究。同时还报道了配体 4a 与 cdk5 的 X 射线坐标,显示了一种通过水分子与 hinge 区结合的不常见的结合模式。
